Nikon is harnessing digicam lens know-how to improve progressive lenses in its eyewear, enhancing distinction and giving wearers clearer imaginative and prescient.
Nikon started making spectacle lenses in 1946, when it launched the Pointal Lens, and in 1983 it launched the primary anti-glare coating with built-in scratch resistance. A right away success in Japan, practically 100% of lenses within the nation now use this resilient coating.
It has now launched its Z Sequence lenses, claiming to forestall presbyopia – an usually pure a part of getting older, whereby the eyes regularly lose their skill to concentrate on close by objects – by specializing in distinction, which is often missing in presbyopia lenses.
Nikon’s eyeglasses are allegedly the primary the place the producer has measured the modular switch operate (MTF) to enhance its lenses – the identical MTF knowledge that has lengthy been used to judge digicam lenses.
MTF testing offers a technique to measure picture sharpness in a repeatable method, measuring the lens’ skill to keep up distinction at particular resolutions.

Through the manufacture of those lenses, the MTF was analyzed at every level within the horizontal and vertical instructions of the lens floor. Utilizing that knowledge, the aberration and optical energy have been tweaked to enhance the distinction.
Generally known as ‘no-line bifocals’, progressive lenses lack the road that travels horizontally throughout the bifocal lens – as such they eradicate the difficulty of the picture soar, wherein photographs seem to jolt whenever you change between the close to and much elements of the lens.

Consequently, although, progressive lenses may trigger peripheral blurriness, or distortion. With the exact manufacturing of Nikon’s lenses as a consequence of measuring the MTF, the distortion is supposedly decreased.
“Nikon has developed a totally new optical design engine that gives optimum distinction by MTF evaluation,” says Nikon on its Z Sequence webpage. “Based mostly on MTF evaluation, aberrations and powers are tuned to a brand new dimension, enhancing distinction.
“The Z collection relieves you from the ‘effort to see’ attributable to presbyopia. It is now simpler to focus in a extra snug place than ever earlier than. You may immediately see what you wish to see, providing you with a free visual field.”
